in the past couple of weeks i've sported both on my toenails, but assuming no one wants to see that, i've spared you the pics. the verdict? both work well as a layer over a darker polish or on their own with a few coats. even though the OPI picture makes it look purply - both truly have assorted color glimmer. however, the winner for me is deborah lippman's happy birthday - the larger chunks of glitter make it that much more unique.
